Having an easy to use and easily accessible defibrillator is one of the most effective ways of treating a cardiac arrest.
It is important that more public places and organisations have these available. This story in the BBC news provides a good read and shows how an emergency can happen at any time.

The chances of of surviving a cardiac arrest are increased if emergency treatment is given as soon as possible. Defibrillators are failsafe, easy to use and will guide the user on how to use them. 
We want your help to spread the word about defibrillators.

We believe every public space should easily have access to a defibrillator. If you believe your workplace, school or club would benefit from having a defibrillator. Recommend an Organisation on http://www.perthdefibrillators.com.au
